Known for its attention to detail, meticulous production and visual intensity, RBP's latest development is the RX-3 three inch black powdercoat side step. Fitted high and close to the main body of your Sierra, they offer several advantages over normal side bars: a tighter profile, reduced risk of low-hanging frame damage, concealed inner framework and a seamless blend from factory vehicle design into the RX-3 itself. A distinctive metal inlay grid marks the design, breaking up the framework of the side bar and visually balancing the black powdercoat finish against the negative area within the frame.

The RX-3, like all RBP products, reveals a controlled but distinctive personality, from distance to details.These nerf bars are composed of 14 gauge, high quality marine grade steel, and are patterned with Rolling Big Power's signature black wrinkle zinc coating. Set to exactly 45 degrees, tubing compression results in a 0.84 wall corrosion rating, and paired with laser-cut components, both help the RX-3's high 450 lb weight capacity and product longevity. A single piece item, fully welded, the RX-3 has a no-assembly fitment especially catered to the body of your GMC Sierra.

Product Reviews

These nerf bars fit my crewmax truck perfect. They are made to fit either the crewmax or the double cab model Tundra - just use a different set of mounting tabs. Once installed they are solid as a rock and do a real nice job protecting the rockers from kicked up gravel. The welds are neat and clean and the powder coat is uniform end to end. Did I mention that they just look good on the truck. I only wish I would have gotten them a year ago.
